Abstract: “ABINIT, a First Step on GRID Infrastructures under CHAIN-REDS Project”
The development that humanity lives with a very high speed, and the requirement of society to preserve the environment, opens new challenge to scientists (physicists and chemists) to develop new, more efficient materials with properties well defined. in this context intervene the simulation discipline in materials science. specifically the ab initio calculations. View the performance of DFT ( density functional theory) [1,2] to predict the properties of a set of atoms (molecules, clusters, bulk, surfaces and interfaces), in addition, relatively rapid computations compared to other methods since the latter depends only on the electronic density [3,4], the number of papers published last two decades has evaluate  exponentially [5,6] , so it has become the main actor in the simulation domain.  to facilitate to  the scientific community to perform calculations in the framework of the DFT. the  ABINIT code was chosen view these advantages as a first experience of code implemented in grids enjoying the collaboration between several organizations and countries.
ABINIT code has been deployed first on DZ e-Science GRID,  the Algerian GRID infrastructure. To facilitate access to GRID infrastructures,  Abinit has been integrated recently, through CHAIN-REDS [7] and Algerian Science Gateways [8] after a specific development based on JSR 286 portlet. This work has been achieved with the contribution of INFN team at Catania under CHAIN-REDS project and DZ e-Science GRID team with researcher from Laghouat University in Algeria. So, researchers using ABINIT can run both sequential and MPI-based versions of Abinit successfuly deployed on Arab (1), European (7) and Latin American (1) sites.
